Wow, that's awesome.
It says in the article..... "Liam's condition is more than a medical rarity: It could help scientists unlock the secrets of muscle growth and muscle deterioration. Research on adults who share Liam's condition could lead to new treatments for debilitating ailments such as muscular dystrophy and osteoporosis."

not only that. Maybe his case could be use to slow human's natural aging process. No more face lifts or botox.

Well, his case could also use for military experiment like creating super soldiers like Captain America. Naah! That's kinda fictional. Too much playing god on that part. I'll just sneak behind these super soldiers and cut their throats. haha. just kidding. ^-^ Or am I not?
